The Corsair Obsidian 550D is constructed primarily of steel, with an aluminum front door. It measures 49.5 x 22.1 x 53.1 cm or 19.5 x 8.7 x 20.9 inches (H x W x D) for a total case volume of 58.1 L and weighs 7.5 kg or 16.5 lb.

The 550D's front door is striking, a solid panel with a pleasant brush aluminum construction. It's about the sturdiest we've seen and it shuts tightly, exposing only the power/reset buttons and audio/USB 3.0 ports.

The interior of the door is lined with noise dampening foam as are the side panels. A plastic cover at the bottom releases with a slight push, revealing two 12 cm intake fans covered with a mesh filter held on by magnetic strips running along the sides. Note: There are vents along the sides of the fan mounts not visible in the image above.

The door is symmetrical and the hinges are held on with screws so it can be flipped to swing open from the opposite side.

The top of the case hides another pair of 12/14 cm fan mounts. Rubber washers are on all 12 cm fan holes except for the ones on the bottom panel.

A side panel fan is counterproductive for a truly quiet chassis. In this case there is an option for a single 20 cm fan or two 12/14 cm models.

At the rear, the expansion slot covers are well-ventilated and there are four watercooling holes on the side. At the top are release buttons for the side panels. There is no need for thumbscrews as access is completely tool-less.

There's another removable dust filter at the bottom of the case for the power supply, and an optional fan mount; It's the only one with a full plastic frame. Toward the front you'll notice four thumbscrews — they hold the bottom hard drive cage in place.
